ところで、回転電機用端末モジュールの形状を円弧状にしようとすると、従来のリング状のものとは異なり回転電機用端末モジュールが厚さ方向の振動により変形しやすくなるという問題があった。そのため、円弧状の回転電機用端末モジュールについて、より振動に強い構造とすることが望まれている。   By the way, when it was going to make the shape of the terminal module for rotary electric machines into circular arc shape, unlike the conventional ring shape, there existed a problem that the terminal module for rotary electric machines became easy to deform | transform by the vibration of thickness direction. Therefore, it is desired that the arc-shaped rotating electrical machine terminal module has a structure that is more resistant to vibration.

本発明は、上述した課題に鑑みなされたものであり、円弧状の回転電機用端末モジュールを厚さ方向の振動により強い構造とすることを主目的とする。   The present invention has been made in view of the above-described problems, and a main object of the present invention is to make an arc-shaped rotating electrical machine terminal module stronger against vibration in the thickness direction.

本発明の回転電機用端末モジュールは、
円弧状の本体部と、
前記本体部に埋設され、該本体部から突出してモータのステータコイルの少なくとも１部を構成する導体と接続される突出部を有する複数のバスバーと、
を備えた回転電機用端末モジュールであって、
前記複数の突出部は、それぞれ、前記本体部の内周面又は外周面から突出しており、前記本体部の一方の端部に最も近い該突出部と、それ以外のいずれか１以上の該突出部とで、前記本体部の厚さ方向の突出位置が異なっている、
ものである。 The terminal module for rotating electrical machines of the present invention is
An arc-shaped body,
A plurality of bus bars having protrusions embedded in the main body portion and protruding from the main body portion and connected to a conductor constituting at least a part of a stator coil of the motor;
A terminal module for a rotating electrical machine comprising:
Each of the plurality of protrusions protrudes from an inner peripheral surface or an outer peripheral surface of the main body, and is closest to one end of the main body, and any one or more of the other protrusions. The protrusion position in the thickness direction of the main body portion is different between the portions,
Is.

この本発明の回転電機用端末モジュールでは、円弧状の本体部に埋設された複数のバスバーが本体部の内周面又は外周面から突出する突出部を有している。そして、この複数の突出部は、本体部の一方の端部に最も近い突出部と、それ以外のいずれか１以上の突出部とで、本体部の厚さ方向の突出位置が異なっている。そのため、本体部の一方の端部に最も近い突出部とそれ以外のいずれか１以上の突出部とで厚さ方向の突出位置が同じであるものと比較して、回転電機用端末モジュールの剛性が高まり、厚さ方向の振動に強い構造とすることができる。ここで、本体部の一方の端部に最も近い突出部とは、本体部の内周面及び外周面のいずれか一方に着目したときに本体部の一方の端部に最も近い突出部としてもよいし、内周面及び外周面の両方に着目したときに本体部の一方の端部に最も近い突出部としてもよい。   In the terminal module for a rotating electrical machine according to the present invention, the plurality of bus bars embedded in the arc-shaped main body has protrusions that protrude from the inner peripheral surface or the outer peripheral surface of the main body. The plurality of protrusions differ in the protrusion position in the thickness direction of the main body portion between the protrusion portion closest to one end of the main body portion and any one or more other protrusion portions. Therefore, the rigidity of the terminal module for a rotating electrical machine is compared with that in which the protruding portion closest to one end of the main body portion and any one or more other protruding portions have the same protruding position in the thickness direction. Thus, a structure strong against vibration in the thickness direction can be obtained. Here, the protrusion closest to one end of the main body is the protrusion closest to one end of the main body when focusing on either the inner peripheral surface or the outer peripheral surface of the main body. Alternatively, the projection may be the closest to one end of the main body when focusing on both the inner and outer peripheral surfaces.

この本発明の回転電機用端末モジュールにおいて、前記複数の突出部は、前記本体部の一方の端部に最も近いｍ個（ｍは２以上の整数）の該突出部が、互いに前記厚さ方向の突出位置が異なっているものとしてもよい。このように本体部の一方の端部に最も近いｍ個の突出部の厚さ方向の突出位置を互いに異ならせることで、回転電機用端末モジュールのうち、特に一方の端部側をより振動に強い構造とすることができる。回転電機用端末モジュールが厚さ方向に振動する場合、本体部が円弧状であるため、本体部の中央部分に比べて端部の方がより振動による変位が大きくなりやすく、結果として端部が振動に弱くなりやすい。そのため、このように端部側をより振動に強くする意義が高い。この場合において、前記複数の突出部は、前記本体部の他方の端部に最も近いｎ個（ｎは２以上の整数）の該突出部が、互いに前記厚さ方向の突出位置が異なっているものとしてもよい。こうすれば、回転電機用端末モジュールの両方の端部側をより振動に強い構造とすることができる。なお、ｎとｍとは同じ値であってもよいし、異なる値であってもよい。ここで、本体部の一方の端部に最も近いｍ個の突出部とは、本体部の内周面及び外周面のいずれか一方に着目したときに本体部の一方の端部に最も近いｍ個の突出部としてもよいし、内周面及び外周面の両方に着目したときに本体部の一方の端部に最も近いｍ個の突出部としてもよい。同様に、本体部の他方の端部に最も近いｎ個の突出部とは、本体部の内周面及び外周面のいずれか一方に着目したときに本体部の他方の端部に最も近いｎ個の突出部としてもよいし、内周面及び外周面の両方に着目したときに本体部の他方の端部に最も近いｎ個の突出部としてもよい。   In the terminal module for a rotating electrical machine according to the present invention, the plurality of protrusions are m (m is an integer of 2 or more) of the protrusions that are closest to one end of the main body. It is good also as a thing from which the protrusion position of differs. Thus, by making the protrusion positions in the thickness direction of the m protrusions closest to one end of the main body different from each other, in particular, one end of the rotating electrical machine terminal module is made more vibrant. It can be a strong structure. When the terminal module for a rotating electrical machine vibrates in the thickness direction, the main body portion is arc-shaped, and therefore, the end portion is more likely to be displaced due to vibration than the central portion of the main body portion. Prone to vibration. Therefore, it is highly significant to make the end side more resistant to vibration in this way. In this case, the plurality of projecting portions of the n projecting portions (n is an integer of 2 or more) closest to the other end of the main body portion are different from each other in the projecting position in the thickness direction. It may be a thing. If it carries out like this, both the edge part sides of the terminal module for rotary electric machines can be made into a structure strong against a vibration. Note that n and m may be the same value or different values. Here, m protrusions closest to one end of the main body are m closest to one end of the main body when focusing on either the inner peripheral surface or the outer peripheral surface of the main body. It is good also as a protrusion part, and it is good also as m protrusion part nearest to one edge part of a main-body part, when paying attention to both an internal peripheral surface and an outer peripheral surface. Similarly, the n protrusions closest to the other end of the main body are n closest to the other end of the main body when attention is paid to either the inner peripheral surface or the outer peripheral surface of the main body. It is good also as n protrusion part, and it is good also as n protrusion part nearest to the other edge part of a main-body part, when paying attention to both an internal peripheral surface and an outer peripheral surface.

本発明の回転電機用端末モジュールにおいて、前記複数の突出部は、前記本体部の一方の端部に最も近いｋ個（ｋは２以上の整数）の該突出部と、前記本体部の他方の端部に最も近いｋ個の該突出部とで、前記厚さ方向の突出位置が対称になっているものとしてもよい。   In the terminal module for a rotating electrical machine according to the present invention, the plurality of protrusions are the k protrusions (k is an integer of 2 or more) closest to one end of the main body, and the other of the main body. The protrusion positions in the thickness direction may be symmetric with the k protrusions closest to the end.

回転電機用端末モジュール３０は、この突出部４１ａ〜４４ａ，４１ｂ〜４４ｂ，４４ｃが各コイルエンド２１ａ〜２６ａ，２２ｂ，２４ｂ，２６ｂと溶接により接続され、引出線用導体５１〜５３の端部５１ａ〜５３ａが各コイルエンド２１ｂ，２３ｂ，２５ｂと溶接により接続されている。また、回転電機用端末モジュール３０は、この各コイルエンド以外のＵ相セグメントコイル２１，２２、Ｖ相セグメントコイル２３，２４、Ｗ相セグメントコイル２５，２６とは接触しないように配置されている。これにより、回転電機用端末モジュール３０は、本体部３２が各コイルエンド以外のＵ相セグメントコイル２１，２２、Ｖ相セグメントコイル２３，２４、Ｗ相セグメントコイル２５，２６からステータ１５の軸方向に離れた状態で支持されている。   In the terminal module 30 for rotating electrical machines, the protruding portions 41a to 44a, 41b to 44b, and 44c are connected to the coil ends 21a to 26a, 22b, 24b, and 26b by welding, and end portions 51a of the lead wire conductors 51 to 53 are connected. To 53a are connected to the coil ends 21b, 23b, 25b by welding. Moreover, the terminal module 30 for rotary electric machines is arrange | positioned so that it may not contact U phase segment coils 21 and 22, V phase segment coils 23 and 24, and W phase segment coils 25 and 26 other than each coil end. Thereby, the terminal module 30 for rotating electrical machines has the main body portion 32 in the axial direction of the stator 15 from the U phase segment coils 21 and 22, the V phase segment coils 23 and 24, and the W phase segment coils 25 and 26 other than the coil ends. It is supported in a separated state.

続いて、第１〜第４バスバー４１〜４４の位置関係について詳細に説明する。まず、本体部３２の周方向の位置関係について説明する。図５に示すように、本体部３２の内周面に着目すると、本体部３２の一方の端部３３（図５における左端）から他方の端部３４（図５における右端）に向かって、突出部４１ａ，４２ａ，４３ａ，４１ｂ，４２ｂ，４３ｂがこの順で本体部３２から突出している。また、本体部３２の外周面に着目すると、端部３３から端部３４に向かって、突出部４４ａ，４４ｂ，４４ｃがこの順で本体部３２から突出している。また、本体部３２の内周面及び外周面の両方に着目すると、端部３３から端部３４に向かって、突出部４１ａ，４４ａ，４２ａ，４３ａ，４４ｂ，４１ｂ，４２ｂ，４４ｃ，突出部４３ｂがこの順で本体部３２から突出している。   Next, the positional relationship between the first to fourth bus bars 41 to 44 will be described in detail. First, the positional relationship in the circumferential direction of the main body 32 will be described. As shown in FIG. 5, when focusing on the inner peripheral surface of the main body 32, the main body 32 protrudes from one end 33 (left end in FIG. 5) toward the other end 34 (right end in FIG. 5). The parts 41a, 42a, 43a, 41b, 42b, and 43b protrude from the main body part 32 in this order. Further, when paying attention to the outer peripheral surface of the main body portion 32, the protruding portions 44 a, 44 b and 44 c protrude from the main body portion 32 in this order from the end portion 33 toward the end portion 34. When attention is paid to both the inner peripheral surface and the outer peripheral surface of the main body 32, the projecting portions 41 a, 44 a, 42 a, 43 a, 44 b, 41 b, 42 b, 44 c, and the projecting portion 43 b are directed from the end portion 33 toward the end portion 34. Protrudes from the main body 32 in this order.

次に、本体部３２の厚さ方向（図７，８の上下方向）における第１〜第４バスバー４１〜４４の位置関係について説明する。図９は、図７と同様に図５のＢ視図であり、厚さ方向の基準面としての本体部３２の底面から突出部４１ａ〜４３ａ，４１ｂ〜４３ｂまでの厚さ方向距離を示す説明図である。図１０は、図８と同様に図５のＣ視図であり、本体部３２の底面から突出部４４ａ〜４４ｃまでの厚さ方向距離の説明図である。本実施例では、本体部３２の底面から各突出部４１ａ〜４３ａ，４１ｂ〜４３ｂ，４４ａ〜４４ｃまでの厚さ方向距離が、距離Ｌ１，Ｌ２，Ｌ３，Ｌ４（Ｌ１＜Ｌ２＜Ｌ３＜Ｌ４）のいずれかとなっている。具体的には、図９に示すように、第１バスバー４１の突出部４１ａは本体部３２の底面からの厚さ方向距離が距離Ｌ１であり、突出部４１ｂは本体部３２の底面からの厚さ方向距離が距離Ｌ３である。第２バスバー４２の突出部４２ａ，４２ｂは本体部３２の底面からの厚さ方向距離が距離Ｌ４である。第２バスバー４２は、本体部３２に埋設された部分も、本体部３２の底面からの厚さ方向距離が距離Ｌ４で一定となっている。第３バスバー４３の突出部４３ａ，４３ｂは本体部３２の底面からの厚さ方向距離が距離Ｌ１である。第３バスバー４３は、本体部３２に埋設された部分も、本体部３２の底面からの厚さ方向距離が距離Ｌ１で一定となっている。第４バスバー４４の突出部４４ａ〜４４ｃは本体部３２の底面からの厚さ方向距離が距離Ｌ２である。第４バスバー４４は、本体部３２に埋設された部分も、本体部３２の底面からの厚さ方向距離が距離Ｌ２で一定となっている。また、図５，６に示すように、第１バスバー４１及び第３バスバー４３は、第２バスバー４２，第４バスバー４４と比べて本体部３２の内周側に埋設されている。第１バスバー４１は、図７に示すように本体部３２の内部において突出部４３ａよりも端部３３側で厚さ方向に屈曲しており、屈曲部を境に端部３３側が突出部４１ａと同じく厚さ方向距離が距離Ｌ１となり、屈曲部より端部３４側が突出部４１ｂと同じく厚さ方向距離が距離Ｌ３となっている。第１バスバー４１はこのように屈曲することで本体部３２内で第３バスバー４３を厚さ方向に避けるように埋設されている。第２バスバー４２と第４バスバー４４とは、厚さ方向距離が異なるため、本体部３２内で厚さ方向に重なるように埋設されている。   Next, the positional relationship between the first to fourth bus bars 41 to 44 in the thickness direction of the main body 32 (the vertical direction in FIGS. 7 and 8) will be described. FIG. 9 is a view as seen in FIG. 5B as in FIG. 7 and shows the distance in the thickness direction from the bottom surface of the main body 32 as the reference surface in the thickness direction to the protruding portions 41a to 43a and 41b to 43b. FIG. FIG. 10 is a C view of FIG. 5 similarly to FIG. 8, and is an explanatory diagram of the distance in the thickness direction from the bottom surface of the main body portion 32 to the protruding portions 44 a to 44 c. In the present embodiment, the distances in the thickness direction from the bottom surface of the main body 32 to the protrusions 41a to 43a, 41b to 43b, and 44a to 44c are distances L1, L2, L3, and L4 (L1 <L2 <L3 <L4). Either. Specifically, as shown in FIG. 9, the protrusion 41 a of the first bus bar 41 has a distance L1 in the thickness direction from the bottom surface of the main body 32, and the protrusion 41 b has a thickness from the bottom of the main body 32. The vertical distance is the distance L3. The protrusions 42a and 42b of the second bus bar 42 have a distance L4 in the thickness direction from the bottom surface of the main body 32. In the second bus bar 42, the portion embedded in the main body 32 also has a constant distance in the thickness direction from the bottom surface of the main body 32 at the distance L4. The protrusions 43a and 43b of the third bus bar 43 have a distance L1 in the thickness direction from the bottom surface of the main body 32. As for the 3rd bus bar 43, the thickness direction distance from the bottom face of the main-body part 32 is also constant at the distance L1 also in the part embed | buried in the main-body part 32. FIG. The protrusions 44a to 44c of the fourth bus bar 44 have a distance L2 in the thickness direction from the bottom surface of the main body 32. In the fourth bus bar 44, the portion embedded in the main body 32 also has a constant distance in the thickness direction from the bottom surface of the main body 32 at the distance L2. As shown in FIGS. 5 and 6, the first bus bar 41 and the third bus bar 43 are embedded on the inner peripheral side of the main body 32 compared to the second bus bar 42 and the fourth bus bar 44. As shown in FIG. 7, the first bus bar 41 is bent in the thickness direction on the end 33 side with respect to the protrusion 43 a inside the main body 32, and the end 33 side is connected to the protrusion 41 a with the bent portion as a boundary. Similarly, the distance in the thickness direction is the distance L1, and the distance in the thickness direction is the distance L3, as is the protruding portion 41b, on the end 34 side from the bent portion. The first bus bar 41 is embedded in the main body 32 so as to avoid the third bus bar 43 in the thickness direction by bending in this way. Since the second bus bar 42 and the fourth bus bar 44 have different thickness direction distances, the second bus bar 42 and the fourth bus bar 44 are embedded in the main body portion 32 so as to overlap in the thickness direction.

第１〜第４バスバー４１〜４４がこのように配置されることで、本体部３２の内周面に着目したとき、本体部３２の端部３３に最も近い突出部４１ａと、他の突出部４２ａ，４１ｂ，４２ｂとで、本体部３２の底面からの厚さ方向距離が異なっている。すなわち、本体部３２の厚さ方向の突出位置が異なっている。また、本体部３２の内周面と外周面との両方に着目したとき、本体部３２の端部３３に最も近い突出部４１ａと、他の突出部４２ａ，４１ｂ，４２ｂ，４４ａ〜４４ｃとで、本体部３２の厚さ方向の突出位置が異なっている。さらに、本体部３２の内周面に着目したとき、本体部３２の端部３４に最も近い突出部４３ｂと、他の突出部４２ａ，４１ｂ，４２ｂとで、本体部の厚さ方向の突出位置が異なっている。また、本体部３２の内周面と外周面との両方に着目したとき、本体部３２の端部３４に最も近い突出部４３ｂと、他の突出部４２ａ，４１ｂ，４２ｂ，４４ａ〜４４ｃとで、本体部３２の厚さ方向の突出位置が異なっている。さらにまた、本体部３２の内周面に着目したとき、本体部３２の端部３３に最も近い２個の突出部４１ａ，４２ａが、互いに厚さ方向の突出位置が異なっている。また、本体部３２の内周面と外周面との両方に着目したとき、本体部３２の端部３３に最も近い３個の突出部４１ａ，４４ａ，４２ａが、互いに厚さ方向の突出位置が異なっている。そしてまた、本体部３２の内周面に着目したとき、本体部３２の端部３４に最も近い３個の突出部４３ｂ，４２ｂ，４１ｂが、互いに厚さ方向の突出位置が異なっている。また、本体部３２の内周面と外周面との両方に着目したとき、本体部３２の端部３４に最も近い４個の突出部４３ｂ，４４ｃ，４２ｂ，４１ｂが、互いに厚さ方向の突出位置が異なっている。そしてまた、本体部３２の内周面に着目したとき、本体部３２の端部３３に最も近い２個の突出部４１ａ，４２ａと、本体部３２の端部３４に最も近い２個の突出部４３ｂ，４２ｂとは、いずれも本体部３２の端部から中央に向かって突出部の厚さ方向距離が距離Ｌ１，Ｌ４の順になっており、厚さ方向の突出位置が対称になっている。また、本体部３２の内周面及び外周面の両方に着目したとき、本体部３２の端部３３に最も近い３個の突出部４１ａ，４４ａ，４２ａと、本体部３２の端部３４に最も近い３個の突出部４３ｂ，４４ｃ，４２ｂとは、いずれも本体部３２の端部から中央に向かって突出部の厚さ方向距離が距離Ｌ１，Ｌ２，Ｌ４の順になっており、厚さ方向の突出位置が対称になっている。   When the first to fourth bus bars 41 to 44 are arranged in this way, when paying attention to the inner peripheral surface of the main body 32, the protrusion 41a closest to the end 33 of the main body 32 and other protrusions The distance in the thickness direction from the bottom surface of the main body 32 is different between 42a, 41b, and 42b. That is, the protruding position of the main body 32 in the thickness direction is different. Moreover, when paying attention to both the inner peripheral surface and the outer peripheral surface of the main body 32, the protrusion 41a closest to the end 33 of the main body 32 and the other protrusions 42a, 41b, 42b, 44a to 44c The protruding position in the thickness direction of the main body 32 is different. Furthermore, when paying attention to the inner peripheral surface of the main body 32, the protrusion 43b closest to the end 34 of the main body 32 and the other protrusions 42a, 41b, 42b protrude in the thickness direction of the main body. Is different. Moreover, when paying attention to both the inner peripheral surface and the outer peripheral surface of the main body 32, the protrusion 43 b closest to the end 34 of the main body 32 and the other protrusions 42 a, 41 b, 42 b, 44 a to 44 c The protruding position in the thickness direction of the main body 32 is different. Furthermore, when paying attention to the inner peripheral surface of the main body 32, the two protrusions 41a and 42a closest to the end 33 of the main body 32 are different from each other in the thickness direction. Further, when paying attention to both the inner peripheral surface and the outer peripheral surface of the main body 32, the three protrusions 41a, 44a, 42a closest to the end 33 of the main body 32 have protrusion positions in the thickness direction. Is different. When attention is paid to the inner peripheral surface of the main body 32, the three protrusions 43b, 42b, 41b closest to the end 34 of the main body 32 are different from each other in the thickness direction. When attention is paid to both the inner peripheral surface and the outer peripheral surface of the main body 32, the four protrusions 43b, 44c, 42b, 41b closest to the end 34 of the main body 32 protrude in the thickness direction. The position is different. Further, when attention is paid to the inner peripheral surface of the main body 32, the two protrusions 41 a and 42 a that are closest to the end 33 of the main body 32 and the two protrusions that are closest to the end 34 of the main body 32. In 43b and 42b, the distance in the thickness direction of the protrusions is in the order of distances L1 and L4 from the end of the main body 32 toward the center, and the protrusion positions in the thickness direction are symmetrical. When attention is paid to both the inner peripheral surface and the outer peripheral surface of the main body 32, the three protrusions 41 a, 44 a, 42 a closest to the end 33 of the main body 32 and the end 34 of the main body 32 are the most. The three adjacent projecting portions 43b, 44c, and 42b all have distances in the thickness direction of the projecting portions in the order of distances L1, L2, and L4 from the end of the main body 32 toward the center. The protruding position of is symmetrical.

こうして構成された回転電機１０は、例えば電気自動車やハイブリッド車に搭載され、引出線６１〜６３が図示しないインバータを介してバッテリに接続されることで、バッテリから電力を入力してモータとして動作したり、バッテリに電力を出力する発電機として動作したりする。このとき、回転電機１０が軸方向すなわち回転電機用端末モジュール３０の厚さ方向に振動する場合がある。この場合において、突出部４１ａ〜４３ａ，４１ｂ〜４３ｂ，４４ａ〜４４ｃの厚さ方向の突出位置が上述したように異ならせてあることにより、突出部４１ａ〜４３ａ，４１ｂ〜４３ｂ，４４ａ〜４４ｃの厚さ方向の突出位置が同じである場合と比較して、回転電機用端末モジュール３０の剛性が高まり、厚さ方向の振動に強い構造となっている。そのため、振動時の回転電機用端末モジュール３０の変形がより抑制される。これにより、例えば突出部４１ａ〜４３ａ，４１ｂ〜４３ｂ，４４ａ〜４４ｃの溶接部分や引出線用導体５１〜５３の端部５１ａ〜５３ａの溶接部分のいずれかに応力が集中して、溶接部分が破断することをより抑制できる。   The rotating electrical machine 10 configured in this manner is mounted on, for example, an electric vehicle or a hybrid vehicle, and the lead wires 61 to 63 are connected to a battery via an inverter (not shown), so that electric power is input from the battery and operates as a motor. Or operate as a generator that outputs power to the battery. At this time, the rotating electrical machine 10 may vibrate in the axial direction, that is, in the thickness direction of the terminal module 30 for the rotating electrical machine. In this case, the protrusions 41a to 43a, 41b to 43b, and 44a to 44c have different protrusion positions in the thickness direction as described above, so that the protrusions 41a to 43a, 41b to 43b, and 44a to 44c Compared with the case where the protruding position in the thickness direction is the same, the rigidity of the terminal module 30 for rotating electrical machines is increased, and the structure is strong against vibration in the thickness direction. Therefore, the deformation of the rotating electrical machine terminal module 30 during vibration is further suppressed. Thereby, for example, stress concentrates on any of the welded portions of the projecting portions 41a to 43a, 41b to 43b, 44a to 44c and the welded portions of the end portions 51a to 53a of the lead wire conductors 51 to 53, so that the welded portions are Breaking can be further suppressed.

以上説明した実施例の回転電機１０によれば、円弧状の本体部３２に埋設された第１〜第４バスバー４１〜４４が本体部３２の内周面又は外周面から突出する突出部４１ａ〜４３ａ，４１ｂ〜４３ｂ，４４ａ〜４４ｃを有している。そして、本体部３２の内周面に着目したとき、本体部３２の一方の端部３３に最も近い突出部４１ａと、それ以外のいずれか１以上の突出部である突出部４２ａ，４１ｂ，４２ｂとで、本体部３２の厚さ方向の突出位置が異なっている。そのため、回転電機用端末モジュール３０の剛性が高まり、厚さ方向の振動に強い構造とすることができる。また、本体部３２の内周面と外周面との両方に着目したとき、本体部３２の端部３３に最も近い突出部４１ａと、他の突出部４２ａ，４１ｂ，４２ｂ，４４ａ〜４４ｃとで、本体部３２の厚さ方向の突出位置が異なっているため、これによっても回転電機用端末モジュール３０を厚さ方向の振動に強い構造とすることができる。さらに、本体部３２の内周面に着目したとき、本体部３２の端部３４に最も近い突出部４３ｂと、他の突出部４２ａ，４１ｂ，４２ｂとで、本体部の厚さ方向の突出位置が異なっているため、これによっても回転電機用端末モジュール３０を厚さ方向の振動に強い構造とすることができる。さらにまた、本体部３２の内周面と外周面との両方に着目したとき、本体部３２の端部３４に最も近い突出部４３ｂと、他の突出部４２ａ，４１ｂ，４２ｂ，４４ａ〜４４ｃとで、本体部３２の厚さ方向の突出位置が異なっているため、これによっても回転電機用端末モジュール３０を厚さ方向の振動に強い構造とすることができる。   According to the rotating electrical machine 10 of the embodiment described above, the first to fourth bus bars 41 to 44 embedded in the arcuate main body 32 protrude from the inner peripheral surface or the outer peripheral surface of the main body 32. 43a, 41b to 43b, 44a to 44c. When attention is paid to the inner peripheral surface of the main body 32, the protrusion 41a closest to one end 33 of the main body 32 and any one or more other protrusions 42a, 41b, 42b. And the protrusion position of the thickness direction of the main-body part 32 differs. Therefore, the rigidity of the rotating electrical machine terminal module 30 is increased, and a structure resistant to vibration in the thickness direction can be obtained. Moreover, when paying attention to both the inner peripheral surface and the outer peripheral surface of the main body 32, the protrusion 41a closest to the end 33 of the main body 32 and the other protrusions 42a, 41b, 42b, 44a to 44c Since the protrusion position in the thickness direction of the main body 32 is different, the terminal module 30 for a rotating electrical machine can be made to have a structure resistant to vibration in the thickness direction. Furthermore, when paying attention to the inner peripheral surface of the main body 32, the protrusion 43b closest to the end 34 of the main body 32 and the other protrusions 42a, 41b, 42b protrude in the thickness direction of the main body. Accordingly, the rotating electrical machine terminal module 30 can be made to have a structure resistant to vibration in the thickness direction. Furthermore, when paying attention to both the inner peripheral surface and the outer peripheral surface of the main body 32, the protrusion 43b closest to the end 34 of the main body 32 and the other protrusions 42a, 41b, 42b, 44a to 44c, Thus, since the protruding position of the main body 32 in the thickness direction is different, the rotating electrical machine terminal module 30 can be made to have a structure resistant to vibration in the thickness direction.

また、本体部３２の内周面に着目したとき、本体部３２の一方の端部３３に最も近い２個の突出部４１ａ，４２ａが、互いに厚さ方向の突出位置が異なっている。これにより、回転電機用端末モジュール３０のうち端部３３側をより振動に強い構造とすることができる。回転電機用端末モジュール３０が厚さ方向に振動する場合、本体部３２が円弧状であるため、本体部の中央部分に比べて端部３３の方がより振動による変位が大きくなりやすく、結果として端部３３が振動に弱くなりやすい。そのため、このように端部３３側をより振動に強くする意義が高い。また、本体部３２の内周面と外周面との両方に着目したとき、本体部３２の端部３３に最も近い３個の突出部４１ａ，４４ａ，４２ａが、互いに厚さ方向の突出位置が異なっているため、これによっても端部３３をより振動に強い構造とすることができる。   Further, when attention is paid to the inner peripheral surface of the main body 32, the two protrusions 41a and 42a closest to the one end 33 of the main body 32 are different from each other in the thickness direction. Thereby, the end part 33 side of the terminal module 30 for rotary electric machines can be made into a structure strong against vibration. When the terminal module 30 for a rotating electrical machine vibrates in the thickness direction, the main body portion 32 has an arc shape, so that the end portion 33 is more easily displaced by vibration than the central portion of the main body portion. The end 33 tends to be susceptible to vibration. Therefore, it is highly significant to make the end 33 side more resistant to vibration in this way. Further, when paying attention to both the inner peripheral surface and the outer peripheral surface of the main body 32, the three protrusions 41a, 44a, 42a closest to the end 33 of the main body 32 have protrusion positions in the thickness direction. Since they are different, the end portion 33 can be made to be more resistant to vibration.

さらに、本体部３２の内周面に着目したとき、本体部３２の他方の端部３４に最も近い３個の突出部４３ｂ，４２ｂ，４１ｂが、互いに厚さ方向の突出位置が異なっている。そのため、回転電機用端末モジュール３０の端部３３側と端部３４側との両方をより振動に強い構造とすることができる。また、本体部３２の内周面と外周面との両方に着目したとき、本体部３２の端部３４に最も近い４個の突出部４３ｂ，４４ｃ，４２ｂ，４１ｂが、互いに厚さ方向の突出位置が異なっているため、これによっても端部３４側をより振動に強い構造とすることができる。   Further, when paying attention to the inner peripheral surface of the main body 32, the three protrusions 43b, 42b, 41b closest to the other end 34 of the main body 32 are different from each other in the thickness direction. Therefore, both the end 33 side and the end 34 side of the terminal module 30 for a rotating electrical machine can be configured to be more resistant to vibration. When attention is paid to both the inner peripheral surface and the outer peripheral surface of the main body 32, the four protrusions 43b, 44c, 42b, 41b closest to the end 34 of the main body 32 protrude in the thickness direction. Since the positions are different, this also makes it possible to make the end 34 side more resistant to vibration.

実施例の回転電機用端末モジュール３０では、本体部３２の内周面に着目したとき、本体部３２の端部３３に最も近い２個の突出部と、本体部３２の端部３４に最も近い２個の突出部とで、厚さ方向の突出位置が対称になっているものとしたが、３個以上の突出部が対称になっていてもよい。また、対称になっていないものとしてもよい。同様に、本体部３２の内周面及び外周面の両方に着目したとき、本体部３２の端部３３に最も近い３個の突出部と、本体部３２の端部３４に最も近い３個の突出部とで、厚さ方向の突出位置が対称になっているものとしたが、２個の突出部のみが対称であってもよいし、４個以上の突出部が対称であってもよい。また、対称になっていないものとしてもよい。なお、本体部３２の外周面に着目したとき、本体部３２の端部３３に最も近いｋ個（ｋは２以上の整数）の突出部と、本体部３２の端部３４に最も近いｋ個の突出部とで、厚さ方向の突出位置が対称になっているものとしてもよい。例えば、突出部４１ａ及び突出部４１ｃの厚さ方向の突出位置を同じとし、突出部４１ｂの厚さ方向の突出位置を突出部４１ａ，４１ｃとは異ならせてもよい。   In the rotary electric machine terminal module 30 according to the embodiment, when attention is paid to the inner peripheral surface of the main body 32, the two protrusions closest to the end 33 of the main body 32 and the end 34 of the main body 32 are closest. The two projecting portions are symmetrical in the projecting position in the thickness direction, but three or more projecting portions may be symmetric. Moreover, it is good also as what is not symmetrical. Similarly, when paying attention to both the inner peripheral surface and the outer peripheral surface of the main body 32, the three protrusions closest to the end 33 of the main body 32 and the three closest to the end 34 of the main body 32 are used. The protrusions in the thickness direction are symmetrical with the protrusions, but only two protrusions may be symmetric, or four or more protrusions may be symmetric. . Moreover, it is good also as what is not symmetrical. When attention is paid to the outer peripheral surface of the main body 32, k protrusions (k is an integer of 2 or more) closest to the end 33 of the main body 32 and k closest to the end 34 of the main body 32. The protrusions in the thickness direction may be symmetrical with each other. For example, the protruding positions in the thickness direction of the protruding portions 41a and 41c may be the same, and the protruding positions of the protruding portions 41b in the thickness direction may be different from the protruding portions 41a and 41c.
